Oxygenation system of aquaculture pond

Abstract

The invention provides an oxygenation system of an aquaculture pond. The oxygenation system comprises photosynthetic bacterium portions, illuminating devices, light barriers, an oxygen supply pipe, first oxygen detection devices, second oxygen detection devices and a power supply device. The photosynthetic bacterium portions are arranged at the bottom of the aquaculture pond and provided with photosynthetic bacteria; the illuminating devices are arranged above the photosynthetic bacterium portions; the light barriers are arranged outside the illuminating devices; the oxygen supply pipe is arranged in the aquaculture pond and comprises a connection pipe and at least two transverse oxygen supply pipes, each transverse oxygen supply pipe is provided with at least one air outlet, one end of the connection pipe is connected with an oxygen supply device, and the other end of the connection pipe is connected to the at least two transverse oxygen supply pipes through normally-closed valves; the first oxygen detection devices are arranged on the at least two transverse oxygen supply pipes and connected with the normally-closed valves; the second oxygen detection devices are arranged at thebottom of the aquaculture pond and connected with the illuminating devices; the power supply device is used for supplying power to the illuminating devices, the first oxygen detection devices and thesecond oxygen detection devices. By adoption of the scheme, layered oxygen supply of the aquaculture pond can be realized.

Description

technical field [0001] The invention relates to the technical field of aeration systems, in particular to an aeration system for a culture pond. Background technique [0002] my country is a big country in the world for aquaculture. The area of ​​pond aquaculture alone reaches about 20 million mu, and the aquaculture output ranks first in the world. Recently, with the continuous expansion of aquaculture area and breeding density in our country, the weather conditions are getting worse and worse, and the requirements for dissolved oxygen of aquatic products are getting higher and higher. Low dissolved oxygen makes it breathe faster, and if it is lower, it will float or even die. [0003] Under normal circumstances, the lack of oxygen in fish ponds is often at night, especially when the air pressure is low at dawn, and the dissolved oxygen is the lowest. Farmers stick to it all night to observe fish schools. The purpose of the aerator is mainly to increase dissolved oxygen int...

AI Technical Summary

Problems solved by technology

[0004] At present, there are a small number of mobile aerators on the market, which do not have the ability to supply oxygen in layers. Under the existing aquaculture mode, aquatic products have high requirements for dissolved oxygen and strong dependence. Insufficient dissolved oxygen will greatly Reduce the production of aquatic products
